DESCRIPTION

Absorbable suture coupling component for a penile prosthesis

An implanted penile prosthesis is effective in relieving erectile dysfunction in men.

An inflatable penile prosthesis typically includes a cylinder that is implanted in each cavernous body of the penis, a fluid reservoir and a pump with valve mechanisms to move the fluid from the reservoir to the cylinder to create an erection in the penis. Other penile prostheses include a malleable cylinder without inflation fluid.

Placing a cylinder in the corpora cavernosa during a typical surgical procedure includes dilating the corpora cavernosa with a dilatation tool to form an implant space sized to receive the cylinder. The cylinder is inserted into the implant space with a needle and a suture. One end of the suture is fixed to the front end of the cylinder and an opposite end of the suture is fixed to a Keith needle. Keith's needle is directed through the glans penis and the cylinder is dragged distally toward the glans penis inside the corpora cavernosa.

WO 2011023197 describes a penile prosthesis comprising a cylinder and a suture coupling component with a suture hole.

The penile prostheses described above have proven effective in relieving erectile dysfunction in men. However, they are welcome by surgeons and patients alike improvements in penile prostheses.

Detailed description

In the following detailed description reference is made to the accompanying drawings, which are part of it and in which specific embodiments are shown by way of illustration in which the invention can be put into practice. In this sense, directional terminology is used, such as "up", "down", "front", "behind", "front", "rear", etc. with reference to the orientation of the figure or figures described. Because the components of the embodiments can be placed in a number of different orientations, the directional terminology is used for purposes of illustration and is by no means limiting. It should be understood that other embodiments can be used and that structural or logical changes can be made without departing from the scope of the present invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

It should be understood that the features of the various exemplary embodiments described herein may be combined with each other, unless specifically indicated otherwise.

The term "proximal" as used in this application means that the part to which reference is made is located next to or near the fixation or origin point or a central point: for example located towards the center of the human body. The term "distal" as used in this application means that the part referred to is located away from the fixation or origin point or the central point: for example located away from the center of the human body. A distal end is the most extreme and furthest position of a distal part of a thing that is described, while a proximal end is the most extreme and closest position of a proximal part of the thing that is described. For example, the glans penis is located distal and the root of the penis is located proximal to the male body, so that the distal end of a cavernous body of the patient extends approximately halfway to the glans penis.

In this specification, "extreme" means more extreme and "extreme part" means that segment of a thing that is adjacent to and extends from the extreme.

In this specification, "substantially constant" in relation to a wall thickness means that the wall is configured to have the same thickness over a given area or part except for production tolerances or acceptable variations in dimensions.

In this specification, "resorbable" indicates a component or material that dissolves in a patient's body tissue over time. By "dissolves" it is understood that the component or material is configured to lose its initial structural integrity and cease to have significant consistency. That is, once dissolved, the component or material no longer provides a structural contribution to the penile prosthesis. The time it takes to dissolve the component or material depends on the type of component or material and its dimensions. It is useful if the

component or material dissolves at the end of a healing period after the implantation of the penile prosthesis. This will vary among patients with different anatoirnas, although typically within 4 to 8 weeks after surgery.

Experience has shown that greater satisfaction is obtained with penile prostheses that include one or two cylinders if the characteristics of the cylinder are not significantly altered on the extension of the cylinder. This is likely because any alteration in such characteristics changes the "sensation" of the erection that can be detected by the patient or his partner during sexual activity. Improvements in penile prosthetic cylinders are possible if an extreme part of the cylinder located in the most distal part of the cavernous body, adjacent to the glans of the penis, is "filled" as much as possible to optimally expand that part of the cavernous body (the part front of the penis expands to the widest possible thickness). Patient information indicates that optimized filling of the distal part of the corpora cavernosa provides a more natural sensation of the erection. Sometimes a pointed or similar piece is used to optimize the filling of the most distal part of the corpora cavernosa.

The embodiments provide a penile prosthesis that can be implanted in the corpora cavernosa of a penis. The penile prosthesis includes a cylinder and a resorbable suture coupling component (RSEC). The RSEC is fixed to an outer surface of the cylinder. The RSEC can be fixed to a suture or similar material to help the surgeon implant and adjust the position of the cylinder in the corpora cavernosa. The RSEC can be biodegraded and then absorbed into the patient's body, leaving the distal end of the cylinder free or not confined to any shape of a pointed piece. In embodiments in which the cylinder is inflatable, the free-pointed part of the cylinder expands as completely and naturally as the other parts of the cylinder to provide the user with a full and expanded cylinder tip to the maximum to improve the thickness and the fullness in the area of the glans penis.

The RSEC allows the surgeon to place the cylinder in the penis with a known surgical approach. For example, the surgeon checks that one end of a suture (a traction suture) is coupled with the RSEC. The traction suture is directed in the distal direction through the glans penis, so that it is possible for the surgeon to pull the traction suture outward from the penis and move the cylinder in the distal direction, that is, towards the more distal part of the corpora cavernosa. The traction suture can be removed to move the cylinder in the distal direction and adjust it to place optimally and fill the most distal part of the corpora cavernosa. The RSEC ensures the possibility of coupling the traction suture with the cylinder without providing a permanent fixation feature that undesirably changes the characteristics of the prosthesis.

The embodiments provide a penile prosthesis that includes a cylinder that has a wall that forms an outer surface of the penile prosthesis and that extends from a proximal end to a distal end of the penile prosthesis with an RSEC attached to the outer surface.

The embodiments provide a penile prosthesis that includes an RSEC, which dissolves inside the corpora cavernosa during the time of healing after surgery.

The embodiments provide a penile prosthesis that is easy to implant and adjust to position it optimally and fill a more distal part of the corpora cavernosa, providing an improved "sensation" of the erection.

The embodiments provide an implantable penile prosthetic system that includes a pump that can be fixed between a reservoir and an inflatable cylinder configured to be placed in a cavernous body of a penis. An RSEc is fixed to an outer surface of the cylinder. The inflatable cylinder of the system is configured to be easily placed in and fill a more distal part of the corpora cavernosa to provide an improved "sensation" of the erection.

Both segments are overmolded with a silicone rubber. It is useful to apply a hydrophilic coating to the outer surface of the silicone rubber. Suitable malleable cylinders are available at Coloplast Corp., Minneapolis, Minnesota.

Figure 8 is a perspective view of an embodiment of a penile prosthetic system 120 that includes a pump 180 connected between a liquid reservoir 182 and an inflatable cylinder 22, the cylinder 22 including a resorbable suture coupling component (RSEC) 24 A tube 184, 186 connects the pump and the cylinders, and the pump and the tank, respectively. In one embodiment, the tube 184 communicates with the inflatable cylinder 22 through a rear tip 21. In one embodiment, the system 120 includes two individual inflatable cylinders 22. The pressure in the pump 180 creates a flow of liquid from the reservoir. 182 to 22 cylinders to create an erection in the penis. Pump 180 may include an activatable valve to release liquid from cylinders 22 so that it flows back to reservoir 182.

In one embodiment, the penile prosthesis cylinder is inflatable. Suitable materials for manufacturing the inflatable cylinder include silicone, polymers such as urethanes, mixtures of urethane polymers, urethane copolymers or the like. Suitable inflatable cylinders are available at Coloplast Corp., Minneapolis, Minnesota. In one embodiment, the pump and the reservoir are manufactured from a material suitable for implantation in the body, such as silicone or the urethane-based materials described above for the cylinder.

In embodiments in which the cylinder 22 is inflatable, the use of the RSEC 24 for the implantation procedure provides an additional advantage in the healing time after the surgery of the prosthesis. The advantage includes that the distal end portion 28 can be expanded to the same level as the remaining part of the cylinder 22 since a permanent suture fixing feature near or at the distal end portion 28 is not required. As the inflatable cylinder 22 is able to expand equally throughout its length, the "sensation" of the erection is more natural. In addition, the part of the prosthesis located in the most distal part of the corpora cavernosa has the same characteristics as the rest of the prosthesis, filling at the same time the space of the corpora cavernosa in, or adjacent to the glans of the penis.

Suitable materials for the absorbable suture coupling component include polyester urethane (PEU), polycaprolactone (PCL), polyglycolic acid (PGA), polylactic acid (PLLA), polydioxanone (PDO) and various copolymers thereof.

The attachment of the RSEC 24 to the cylinder 22 can be achieved in different ways, including bonding with adhesive of the RSEC 24 on the cylinder by a solvent bond or using a PU adhesive in embodiments where the cylinder is also made of a PU. In one embodiment, RSEC 24 is created directly from reabsorbable liquid PEU precursors on the cylinder PU surface instead of providing RSEC 24 separately and fixing it. In one embodiment, the RSEC 24 is provided as a ring 34 that mechanically adheres by making an inner diameter of the ring 34 slightly smaller than an outer diameter of the cylinder 22 (at the desired location of attachment). By applying a solvent to the ring, the ring swells allowing it to be placed around the surface of the cylinder. When the solvent vaporizes, the ring recedes and adheres by mechanical and van der Waals forces.

10 Embodiments have been described in which a penile prosthesis includes a resorbable component for coupling with a suture used to pull the penile prosthesis distally to the corpora cavernosa of a penis. The resorbable component dissolves during the healing time after surgery and helps the penile prosthesis to be easily placed and adjusted without the need for permanent suture fixation elements in the prosthesis to allow the surgeon to pull the prosthesis distally. This in turn ensures a penile prosthesis with little or no influence on the features of the longitudinal extension of the surface of the penile prosthesis.
